Benefits of technology

The patent describes a method, apparatus, and computer-readable media that can modify a group call to include device-to-device communication. This involves initiating a group call, monitoring a multicast downlink bearer for a signal related to the group call, and controlling the device-to-device cluster establishing for the user equipment based on a reference signal. The technical effect of this embodiment is the efficient and effective facilitation of device-to-device communication in a group call setting.

Problems solved by technology

However, current LTE does not support advanced direct device to device (D2D) communication and mission critical voice group call, but only voice group call with a conference call type application.

Embodiment Construction

:

[0023]Certain embodiment relate to advanced direct device to device (D2D) communication and mission critical voice group call, for example, for long term evolution (LTE). Thus, certain embodiments can help a public safety network (PSN) to be fast, reliable, and secure, despite lack of network coverage, lack of network resources, or any type of network failure. In certain embodiments, the group call users establish D2D clusters and only the D2D cluster head CH keeps an active uplink radio bearer (RB) towards the network for possible uplink voice stream transmission when one of the cluster members speaks. Thus, certain embodiments dynamically configure the UE for reference signal transmission and for monitoring the reference signal to setup the cluster based on involvement of the group call.

[0024]In general, a voice group call can be supported over an LTE network with a conference call, or similar, application. However, for each member of the conference call, an individual evolved pa...

Abstract

Public safety networks, such as long term evolution (LTE) based public safety networks, can benefit from device to device enhanced voice group call. A method can include serving at least one user equipment. The method can also include controlling device-to-device cluster establishing for the at least one user equipment based on at least one reference signal. This use of device-to-cluster establishment based on at least one reference signal can be applied in various ways, including being applied to group calls.

Description

BACKGROUND[0001]1. Field[0002]Public safety networks, such as long term evolution (LTE) based public safety networks, can benefit from device to device enhanced voice group call.[0003]2. Description of the Related Art[0004]In order to use long term evolution (LTE) of the 3rd Generation Partnership Project (3GPP) for a mobile broadband public safety network (PSN), various functionalities may be useful or important. In general, in a PSN speed of connection in terms of set time, rate, and so on, as well as reliability and security may be important features, regardless of network coverage issues, resource scarceness, or any type of network failure. However, current LTE does not support advanced direct device to device (D2D) communication and mission critical voice group call, but only voice group call with a conference call type application.SUMMARY[0005]According to certain embodiments, a method includes serving at least one user equipment. The method also includes controlling device-to...
